Modular sewing machine

Abstract

An improved modular sewing machine which has a base unit including a lower horizontal unit and a vertical upright unit to which can be attached demountable upper and lower stitching instrumentalities, the mounting surfaces of the stitching instrumentalities being substantially coplanar.

We claim: 
     
       1. An improved modular sewing machine frame comprising: (a) a base member having a vertically extending planar mounting surface formed on one side thereof;   (b) a lower horizontal base unit carrying lower stitching instrumentalities demountably secured to said mounting surface of said base member and providing a work supporting surface;   (c) a vertical upright extending upwardly from said base unit and including a horizontal arm that extends outwardly in overlying relationship with respect to said horizontal base unit and the work supporting surface thereof, said horizontal arm terminating in a vertically extending planar mounting surface that is substantially coplanar with the said mounting surface of said base unit; and   (d) a head unit carrying upper stitching instrumentalities adapted to cooperate with the lower stitching instrumentalities to form stitches, said head unit being demountable secured to said planar mounting surface of the horizontal arm of said vertical upright.
